 ## Features
 
-- view and time constrains
+- server cannot decrypt contents due to client side encryption
+- view or time constraints
 - in memory, no persistence
-- in browser encryption → server cannot decrypt contents
 - obligatory dark mode support
 
 ## How does it work?
 
-each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory and never persisted to disk.
+each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The
+<code>id</code>
+is used to save & retrieve the note. the note is then encrypted with aes in gcm mode on the
+client side with the <code>key</code> and then sent to the server. data is stored in memory and
+never persisted to disk. the server never sees the encryption key and cannot decrypt the contents
+of the notes even if it tried to.

-# create-svelte
-
-Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/master/packages/create-svelte);
-
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```bash
-# create a new project in the current directory
-npm init svelte@next
-
-# create a new project in my-app
-npm init svelte@next my-app
-```
-
-> Note: the `@next` is temporary
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-
-```bash
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
-```
-
-## Building
-
-Before creating a production version of your app, install an [adapter](https://kit.svelte.dev/docs#adapters) for your target environment. Then:
-
-```bash
-npm run build
-```
-
-> You can preview the built app with `npm run preview`, regardless of whether you installed an adapter. This should _not_ be used to serve your app in production.

-		<i>cryptgeon</i> is an secure, open source sharing note service inspired by
-		<a href="https://privnote.com"><i>PrivNote</i></a>.
-	</p>
-
-	<p>
-		<b>▶ how does it work?</b>
-		<br />
-		each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory
-		and never persisted to disk.
-	</p>
-
-	<b>▶ Features</b>
-	<ul>
-		<li>view and time constrains</li>
-		<li>in memory, no persistence</li>
-		<li>in browser encryption → server cannot decrypt contents</li>
-	</ul>
-
-	<p>
-		<b>▶ tech stack</b>
-		<br />
-		the backend is written in rust and the frontend is svelte and typescript.
-		<br />
-		you are welcomed to check & audit the
-		<a href="https://github.com/cupcakearmy/cryptgeon" target="_blank" rel="noopener">source code</a

+			each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The
+			<code>id</code>
+			is used to save & retrieve the note. the note is then encrypted with aes in gcm mode on the client
+			side with the <code>key</code> and then sent to the server. data is stored in memory and never
+			persisted to disk. the server never sees the encryption key and cannot decrypt the contents of
+			the notes even if it tried to.
